BUILDER? MECHANISM` FOR SPINNING AND LIKE MACHINES.

.Application filed Mayl, 1925. Serial' No. 30,6921

To aZZw/om zf may concern:

Be it known that'lf, ELLIS HAnrLnY, a subject of the King of Great Britain, residing at l/Vhitinsville, in the county ofWV'orcester and Commonwealth of Massachusetts, have invented certain new and useful" Improvements in Builder Mechanisms for Spinning and like Machines, of which the following is a specification.

This invention to be hereinafter described relates tofcap spinning machines, and more particularly to the means for locking the builder mechanisms of such machines.

ln cap spinningI machines as. at present constructed, part of the builder mechanism comprises a: revolvabl'e shaft with a sleeve slidably mounted thereon and cooperating therewith by means of a spline fixed to the shaft. Rotary -mot'ionv is imparted to the sleeve by means-of a gear fixed to the sleeve and while the bobbins are being filled cooperates witli a gear rotatable on a stud fixed to the machine frame and' deriving its motion from an adjacent power transmitting mechanism .of the machine. Normally the sleeve gear is held in operative position by means of a locking member comprising a latch swingable on a stud fixed' to the framing of the machine and cooperating with a groene inthe sleeve.

When the bobbins have been filled and are ready to be dolfed the operative disengages the latch and slides the sleeve gear from its meshing relation with its driving gear after Which by means of a hand wheel attached to the end of the sleeve he turns the shaft so as to pro erly position the bobbin rails to facilitate t e removal of the filled bobbins and the replacement of empty ones.

When this is accomplished he pushes the sleeve gear into its normally operative position and sometimes neglects to return the latch to its locking position with the result that the sleeve gear slips from engagement with the driving gear causing a breakage of the yarn and damage to parts of the machine. By means of my invention this objectionable construction is eliminated thus resulting in preventing waste and the avoidance of requirements for repairs.

The novel features of my invention will be apparent fromy the following description taken in connection withA the drawings:

lnthe drawings:

Figures 1 andV are respectivelyA a front elevation and an end elevationof a. portion of' a spinning machine with parts broken awayV and parts omitted tov show the relative position of my" improvement inthe machine. Figure 3 is a section on line--Sl of- Figure'- 2. Figure 4e is an enlarged eleva-tion of my improved locking-r device. i

My' inventionL is herein illustrated asl applied to a cap spinning machine havingl an` end frame 1.0 supporting' 'a stationaryspindle rail 11 onwhich are stationeda plura-lty of spindles 12 carrying caps 13, and 14 is the bobbin rail carrying the bobbintubes 15 which are raised and lowered by thel motion imparted by the usual typeV of' builder mechanism, which includes aV sleeve 16 revolvable in bearing 17 forming a part of bracket 2-1- fixed to the frame 10.l The sleeve 16 .is slidably mounted on the builder shaft 18 and revclvable therewith by means of the splines 19 fixed to the'sleeve and slidable in ways planed in the shaft.

Rotary' motion is imparted to thesleeve and thence to the shaft by a gear 20 fastened to the sleeve, and meshing with gear 21 which derives vits inactionv from power transmitting means not shown in they drawings. A transverse groove 22 c'ut in the hub of gear 2O coacts with the locking member 23 slidably mounted in the bracket 24 to lock the sleeve in its normally operative position. The locking member is normally maintained in its locking position by a resilient member 25 abutting between a lug 26 on the locking member 28 and the inner flange 27 of the bracket 24. Preferably the resilient member is a coiled wire spring slidably mounted on the stud 28, one end of which is fixed in the bracket flange 27 and the other end loosely passes through a hole in the lug 26. The locking member is slidably held in the bracket 24 by means of the retaining cap 29 fastened to the bracket 24 by the bolt 30 and passing through the slot 31 in the locking member 23.

In the operation of dong it is necessary to disconnect the power transmitting means from the builder motion to enable the operative to position the bobbin rail. This he accomplishes by first releasing the locking member 23 from its contact with the groove 22, secondly by sliding the sleeve gear'2() from its meshing contact with the driving gear 2l and thirdly manually rotating the hand wheel 32, fastened to sleeve gear so vthat motion is communicated to the builder shaft and thence through the usual connections of the ordinary type of builder motions, the bobbin rail is set in proper position. To facilitate the release of the member 28 from its locking relation with the sleeve gear, manually operative means are provided, preferably I 'use a rack 33 cut or affixed to the back of the locking member 23 and cooperating with a pinion 34 fixed to shaft 35 rotatable in bearings maintained in the bracket 2li. By means of a handle 86 fixed to the shaft. 35 the operative with one hand readily raises the locking member against the resistance of the compression spring 25 sufficiently high to release it from Contact with the groove 22 and with his other hand pulls the sleeve gear out from its meshing contact with the driving gear; the operative then relinquishes his hold on the handle 36 and the lower end of the locking member is forced by the compression spring 25 into Contact with the tapered end 37 of the sleeve gear hub.

After the bobbins are doffed and before starting the machine the operative pushesV the sleeve gear into engagement with its driving gear, by so doing the locking member by means of the compression spring,

automatically snaps into engagement with the groove in the hub of the sleeve gear and the machine may be started without breaking the yarn or damaging the machine.

I claim:

1. The combination with a cap spinning machine having a movable bobbin rail and mechanism for raising and lowering said rail including a revolvable shaft, of a sleeve revolvable with and slidably mounted on said shaft, a driving gear, a gear fixed to the sleeve in position to engage and disengage said driving gear as the sleeve is slid along the shaft, a transverse groove in the sleeve, a member slidably mounted in a bracket fixed to the framing of the machine and cooperating with said groove to lock the sleeve gear and driving gear in normally operative position, means to normally maintain said member in its locking position and manually operative means to release said member from its locking engagement with said sleeve.

2. The combination with a cap spinning machine having a movable bobbin rail and mechanism for raising and lowering said rail including a revolvable shaft of a sleeve revolvable with and slidably mounted on said shaft, a driving gear, a gear fixed to the `its locking position, a shaft supported in bearings of said bracket, a pinion fixed to said shaft, a rack in a fixed relation with ,y

said locking member cooperating with said pinion and a handle on the pinion shaft whereby the locking member may be released from its locking position.

In testimony whereof, I have signed this specification.

ELLIS HARTLEY.
